CATCH-BASIN oovea.

SPECIFICATION forming part of Letters Patent No. 374,393, dated December6, 1887.

Application filed March 14. 1887.

To all whom it may concern.-

ISeit known that I, GEORGE G. CAMPBELL, of Milwaukee, in the county ofMilwaukee and State of Wisconsin, have invented new and usefulImprovements in Catch-Basin Covers; and I do hereby declare thefollowing to be afull, clear, and exact description of said invention,reference being had to the accompanying drawings,and to the lettersorfigures of reference marked thereon, which form a part of thisspecification.

My invention relates to improvements on the catch-basin cover for whichI obtained United States Patent No. 204,882 on June 18, 1878.

The object of my improvements is to provide a cover so constructed as tobe adjustable in height, whereby the cover is adapted for use inconnection with curbing of different heights.-

In the drawings, Figure 1 is a single catchbasin cover of the form usedat the corner of the curbing at streetcrossings. Fig. 2 is a cover witha straight face adapted to be used with straight curbing, which coverhas also an extension or double cover top. Fig. 3 is also a cover with astraight face and with two extensions of the double cover top. Fig. 4 isa vertical section of the cover shown in Fig. 3 on line 00 mthereof.Fig. 5 is a vertical section of a modified form of cover. 7

The same letters refer to like parts in all the views.

The catch-basin cover is constructed ofcastiron, and the main part A iscastin one piece, the man-hole cover B being cast separately. The innertop edge, 0, of the cover is, for convenience of construction and forstrength and neatness of appearance, curved,while the top outer edge ismade to conform with and form a part of the line of the curbings, beingfor a corner basin constructed with an angle, D, as shown in Fig. 1, andfora straight curbing is constructed with a straight edge, E, as shownin. Figs. 2 and 3. The guards F F project outwardly, downwardly, andobliquely, forming a curved guard'line,G,at their lower ends.

It frequently occurs that the curbing H of the street is so high as toextend above a cover made as shown in Fig. 1 when prop- Serial No.230.817. (No model.)

erly set with reference to the surface of the ground for taking thesurface-water therefrom, and to provide for obviating that objectionablefeature and to provide a comparatively inexpensive extension upward ofthe top of the cover, whereby the surface of the top of the cover can bemadeflush with the top of the curbing H, I use one or more sections ordouble covers, I I, with flanges or sides K K, of greater or lessheights, as required, these sections being of the same size and form asthe top of the cover proper, A. These extensionsections of cover I I arealso made of cast-iron, and one, as shown in Figs. 2 and 5, or more, asshown in Figs. 3 and 4t,fn1ay be used, as required, to bring the topsurface of the cover flush withthe top of the curbing. The top surfaceof the main cover A and of each of the intermediate covers or sectionsis provided with lugs or guards L L integral therewith, adapted toreceive against them the inner sur face of the sides K K at their loweredges and hold the sections I I in place against slipping or movingthereon. The extension-section is bolted at M M to the main or bottomcover,A. These extensionsections may be made of different thicknesses,so as to be adapted for use with curbing of varying heights.

If it be desired to construct mason-work about and above the main cover,the extension-section I can be made in the form shown, Fig. 5that is tosay, with its side walls, K

K, close about the man-hole, the top flange or cover being turnedoutwardly to receive the bolts M M.

IVhat I claim as new,and desire to secure by Letters Patent, is

1. In catch-basin covers, an extension top section or cover, I,supported on the main cover A, substantially as described.

2. In catch-basin covers, a main cover, A, provided with guards L L, andan extensioncover, I, placed and supported on the main cover A, andsecured thereto by bolts or equivalent means, substantially asdescribed.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE G. CAMPBELL.
